Nav voice volume...up and down
Just discovered this today (730N RHR) that if you use the volume control on the steering wheel while the Nav lady is speaking you can make her louder or quieter and that sets the Nav lady voice volume...until you change it again. No need to go into the media center menu etc.....
Dunno....thought that would be helpful.
